Summary

call [System.Text.Json.JsonSerializer]::Serialize in a powershell script. The script runs ok in VS code. But after editing anything in the script, the script failed at the call of [System.Text.Json.JsonSerializer]::Serialize. No issue if run the modified script in pwsh directly.

Steps to Reproduce

testJson.zip
testJson.ps1 in the zip can run no problem in VS Code with output

this1:
{"FirstName":"John","LastName":"Doe"}

But if remove 1 in "this1", and run the script again in VS code, got output as
Line |
24 | $jsonString = [System.Text.Json.JsonSerializer]::Serialize[Person]($p …
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
| Could not find a suitable generic method overload for "Serialize" with "1" type parameters, and the argument count: "1".
this:

No issue to run the modified script in pwsh. Something is wrong in Powershell extension.

[SydneyhSmith]

Thanks @hshenMcc are you able to provide your entire script?

[SeeminglyScience]

Ah nevermind the above message @hshenMcc, in the triage meeting I didn't see you had already provided the script

[SydneyhSmith]

We we're able to reproduce this outside of VSCode so it is a PowerShell issue-- @SeeminglyScience is going to create an issue in PowerShell/PowerShell

Where ever the issue is, which release on which product (VS Code/Powershell) has the fix? Thanks.

[JustinGrote]

@hshenMcc there is no fix yet but if there is one, it will land in PowerShell and (hopefully) be available in the next release after that, which is currently PS7.5. The vscode side will "just work" when that's completed.
